Trust me, I have identified the whole of the problem after enabling full
trace of the relevant scripts and going through the logs with a fine
tooth comb.  The bug is not *in* Ubiquity therefore it is incorrect to
leave it tasked there.  The Ubiquity developers do not need to know
about it as they can not fix it.  It also would still say there is a
problem in ubiquity after it is fixed in partman-crypto.  Unfortunately
launchpad does not have the capability to record that a bug affects
another package without actually being in that package and needing to be
fixed in that package.


** No longer affects: ubiquity (Ubuntu)

Title:
  Can't install /home into separate LUKS encrypted volume

Status in partman-crypto package in Ubuntu:
  Triaged

Bug description:
  For various reasons, I would prefer not to use the default full disk
  encryption method (which relies on LVM) when installing Ubuntu.
  Rather, I would prefer to install directly into multiple LUKS-
  encrypted volumes.

  Using the “something else” option presented during installation of
  15.10 and 16.04 (onto a non-UEFI system with a gpt formatted drive), I
  have been able to create a LUKS-encrypted volume on sda2, and I have
  been able to install boot (/boot) into non-encrypted sda1, and root
  (/) into LUKS-encrypted sda2.   All is good in that simple situation.
  (To get this to work, I skip creating a swap partition, and then
  create a swap file in sda2 after installation has completed.)

  However, when using the “something else” option presented during
  installation of 15.10 and 16.04, after creating LUKS-encrypted volumes
  on sda2 and sda3, I have not been able to install boot (/boot) into
  non-encrypted sda1, root (/) into LUKS-encrypted sda2, and home
  (/home) into into LUKS-encrypted sda3.  Rather, although I am able to
  create the LUKS-encrypted volumes, the installer hangs during
  installation when the following is displayed:

  “Creating ext4 system for /home in partition #1 of Encrypted volume
  (sda3_crypt)...”

  For what its worth, I am able to accomplish the above installation
  (/home on LUKS-encrypted sda3) using the net-installer for 15.10.
  Also, I was able to accomplish the above installation (/home on LUKS-
  encrypted sda3) using the graphical installer for 15.04.  So it seems
  that some sort of regression has crept into the graphical installer
  for 15.10 and 16.04.
